This paper addresses Colin Holmes's suggestion that the psychopathic disorder is best regarded not as a psychiatric concept, but as an ethical one. The paper argues that the concept of psychopathy, like many other concepts, can span both psychiatry and ethics, and that it is not clear what removing if from the realm of psychiatry would entail. Also, the question of whether the concept of psychopathy is useful for psychiatrists must be separated from the question of whether psychopaths should be exonerated from the moral and legal responsibility for their actions
